Family Hemileuddm. Packari)(1914, p. 77-151, PI. XX-XXXI). 



Fracker (1915, p. 122). The setae are partly bifurcated and 

 8ituatiH] on very long and thin tubercula, some of them bear a 

 «pino8e character and are short and forked. The latter are developed 

 fronj the former e.g. Heniilcuca inaiu. (Packard, 1914, PI. XXII). 



They are arranged as on the Saturniidae i. e. Type la. S. dor- 

 sitlis is still to be found on the abdomen of Pseudohasis eglanterina. 



Family Saturnidae. Weismann (1876) drew attention to the 

 spots which on the larvae are different according to their places 

 of birth. I therefore thought it right to draw these spots in their 

 exact shape. Plate III, fig. 14, 15. 



Packard (1914, PI. XXVI— XXXIII and p. 151—271). Tracker 

 (1915, p. 121 — 122). As early as in instar / the larvae have 

 verrucae which later on become scoli. Secondary setae sometimes 

 make the arrangement a little indistinct. Generally the scoli 

 consist of a conical tuberculum on the top of which some (2 — 10) 

 setae take their origin. The setae often end in a knob and they 

 are glandular hairs. In the successive moults the number of setae 

 often diminishes. On abdominal segment 8 the sc. dorsales are 

 placed close together. Naked forms are also found, but the first 

 instars have the above mentioned scoli e. g. Rhodia fugax (Packard 

 1914, PI. XXVIII— XXIX). — PouLTON (1890) mentions depressed 

 scars on the pupa of Satuniia carpina. To me it seems that the Hemi- 

 leucidae and the Satinitidae are side-branches, not directly connected 

 with the Sphingidae. The description of Saturnia pavonia follows. 



Saturnia pavonia. Plate III, fig. 14, 15. 



Material in alcohol, cultivated at Groningen in the summer of 1915. 



Instar /. Length 3'/2 m™- Head black. The tubercula are 

 warts, mostly with 5 — 7 not plumed setae, which have a length 

 of ± 700 fji.. On the skin there are no other setae. 



Prothorax. V, dorsalis, seta subdorsalis, v. suprastigmalis, s. pro- 

 stigmalis^ v. hasalis with two setae. 



Mesothorax and Metathorax. V. dorsalis, v. suprastigtnalis, 

 V. poststiginalis, v. hasalis with two setae, s. dorsolateralis.
